Bambu A1 combo with dryer. Modified AMS lite 4 color printing. Rear mounted spool holder to save on space. Upgraded cool plate. Panda Knomi display (customizable graphics). Locking spool holder with metal ball bearings. Printer works flawlessly. A Comgrow filament dryer comes with it. Dries 2 spools at a time, dries major filament types including TPU. I have had No problems with this printer, just hit print and walk away knowing i'll come back to a perfect print.
